Application and quantum properties of superpositions of oppositely squeezed states
Hiroo Azuma, William J. Munro, Kae Nemoto
We show that superpositions of oppositely squeezed states -- non-Gaussian Schr{ö}dinger-cat-like states -- exhibit enhanced nonclassical features and provide an entanglement advan…
Coherence-Enhanced Quantum Battery Charging with Ergotropy Stabilization
Fan Yang, Hui Wang, Yusef Maleki +3
Quantum batteries utilize nonclassical resources to achieve charging speed and energy storage performances that surpass classical thermodynamic limits. However, the practical reali…
Adaptive Resource and Memory Control for Stability in Quantum Entanglement Distribution
Nicolò Lo Piparo, William J. Munro, Kae Nemoto
We investigate congestion-aware control of quantum repeater nodes operating under stochastic traffic and finite memory coherence. Entanglement generation is modeled as a probabilis…
Use of Faulty States in Cat-Code Error Correction
Michael Hanks, Soovin Lee, Nicolo Lo Piparo +4
Bosonic codes have seen a resurgence in interest for applications as varied as fault tolerant quantum architectures, quantum enhanced sensing, and entanglement distribution. Cat co…
Quantum Random Features: A Spectral Framework for Quantum Machine Learning
Akitada Sakurai, Aoi Hayashi, William John Munro +1
Quantum machine learning (QML) models often require deep, parameterized circuits to capture complex frequency components, limiting their scalability and near-term implementation. W…
Powering Quantum Computation with Quantum Batteries
Yaniv Kurman, Kieran Hymas, Arkady Fedorov +2
Executing quantum logic in cryogenic quantum computers requires a continuous energy supply from room-temperature control electronics. This dependence on external energy sources cre…
